General Maintenance; Maintenance; Lubrication; Replacing The Cutting Blades - Ryobi RY401020 Manuel D'utilisation

WARNING:
Before performing any maintenance or cleaning the lawn
mower, make sure the mower blade comes to a complete
stop and the batteries and start key are removed to avoid
accidental starting and possible serious personal injury.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts can create a hazard or cause
product damage.
WARNING:
Never use a hose, water, or any liquids to clean or
rinse off the lawn mower. Corrosive liquids, water, fer-
tilizers, and chemicals used to treat lawns can enter the
lawn mower and/or battery compartment and damage
electronic components and/or the battery packs, which
can result in a short circuit, increased risk of fire, and
serious personal injury. Remove any buildup of grass
and leaves on or around the mower housing and/or un-
derneath the mower deck. Wipe the mower clean with a
dry cloth occasionally.
NOTICE:
Periodically inspect the entire product for damaged,
missing, or loose parts such as screws, nuts, bolts, caps,
etc. Tighten securely all fasteners and caps and do not
operate this product until all missing or damaged parts
are replaced. Please contact customer service or an
authorized service center for assistance.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.

MAINTENANCE

WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken, or
destroy plastic which can result in serious personal injury.

LUBRICATION

All of the bearings in this product are lubricated with a suf-
ficient amount of high grade lubricant for the life of the unit
under normal operating conditions. Therefore, no further
bearing lubrication is required.
WARNING:
Always protect hands by wearing heavy gloves and/or
wrapping the cutting edges of the blades with rags and
other material when performing blade maintenance. Con-
tact with the blades could result in serious personal injury.

REPLACING THE CUTTING BLADES

See Figures 15 - 16.
NOTE: Only use authorized replacement blades.
 Stop the motor and remove the start key. Allow the blades
to come to a complete stop.
 Remove the battery packs from the battery port.
 Turn the mower on its side.
 Wedge a block of wood between the blades and mower
deck to prevent the blades from turning.
 Loosen the blade nut by turning it counterclockwise (as
viewed from bottom of mower) using a 15 mm wrench
or socket (not provided).
 Remove the blade nut, spacer, blade insulator, and blades.
Do not remove the hub or the adaptor.
 Inspect the blades and replace one or both as needed.
WARNING:
If the hub and/or the adaptor have been removed, replace
them before placing blades on the shaft. Failure to do so
could cause the blades to detach or become unbalanced
since blades will not tighten properly, which can result in
serious personal injury.
 Place the new blade on the shaft against the blade posts
on the hub. Ensure blades are properly seated with shaft
going through center blade hole and the two blade posts
on the hub inserted into their respective holes on the
blades. Make sure it is installed with the curved ends
pointing up toward the mower deck and not down toward
the ground. When seated properly, the blades should be
flat.
